UNITED STATES PATENT UEEIGE VENTILATOR.

Specification of Letters Patent.

Patented Oct. 17, 1905.

Application filed January 31, 1905. Serial No. 243,520.

To all whom it may concern.-

Be it known that I, SUMNER L. MORSE, a citizen of the United States, residing at Athol, in the county of Worcester and State of Massachusetts, have invented a new and useful Ventilator, of which the following is a specification.

This invention relates to ventilators, and is designed to provide an improved device of this character which is entirely complete in itself and capable of being placed beneath and also above a partially-open windowsash, so as to control the assage of air through the opening. at the bottom or the top of the sash and also to provide for defleeting the incoming air upwardly and over the head of a person situated adjacent the window, thereby to avoid a directdraft.

Another object of the invention is to provide for the convenient adjustment of the device to fit windows of different widths without impairing the controlling of the aircurrent.

With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particu larly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings, Figure 1 is a front elevation of the bottom ortion of a window having the ventilator of thepresent invention fitted beneath the lower sash. Fig. 2 is an enlarged longitudinal sectional view on the line 2 2 of Fig. 1. Fig. 3 is a cross-sectional view on the line 3 3 of Fig. 2. Fig. 4 is a detail perspective view looking at the inner sides of the inner ends of the slid- Fig. 5 is a front elevation of the body of the device with the slidable members removed.

Like characters of reference designate corresponding parts in each and every figure of the drawings.

The device of the present invention comprises a back or body 1 preferably in the nature of an oblong wooden plate or bar of suitable dimensions and of a length to fit within a comparatively narrow window. Sets of perforations 2, 3 4, and 5 are formed through the back or body 1 at suitable intervals, each undercut for the set preferably including four perforations arranged around a common center. Some of the sets of perforations, preferably the two middle sets, are each provided with an adjustable closure or valve 6, preferably in the nature of a metallic disk let into a recess in the front of the body, so as not to project at said front and rotatable upon a central fastening 7, there being an annular series of openings 8 in the plate for alternate registration and non-registration with the perforations in the body, thereby to close said perforations, as desired. Each cut-off or 010- sure 6 is provided with a projection 9, constituting a handle or finger-piece for the rotatable adjustment of the cut-off.

Mounted upon the front of the body 1 are two slides, (designated 10 and 11, respectively) he Slide 11 being shorter than the slide 10 and located at the right-hand end of the body 1. For slidably connecting the members 1 and 11 the front of the member 1 is provided adjacent its top with a longitudinal groove 12, which is laterally inclined or [reception of a correspondingly-inclined projection or rib 13, carried in a groove 14 in the inner side of the member 11 and corresponding to the groove 12, there being a set-screw 15 piercing the top edge of the member 11 and engaging the rib or tongue 13, so as to rigidly hold the latter in place. In the righthand end of the groove 12 in the member 1 there is a rib or projection 16, held in place by a set-screw 17, said rib or tongue working in the groove 14 and constituting a stop for engagement by the rib 13 to prevent separation of the members 1 and 11. The member 11 is also provided with another longitudinal laterally-inclined groove 18 in the lower portion of its inner face for the reception of a correspondinglyinclined tongue or rib 19, carried by the lower portion of the inner face of the member 1 and extending throughout the entire length thereof. By reason of thelateral inclinations of the engaged grooves and ribs the members 1 and 11 are held against lateral separation, while at the same time the member 11 is capable of being slid in an endwise direction upon the member 1. In addition to the ribs and grooves the member 11 is also pro- 'vided with two longitudinal series of perforations 20 for successive alinement with the perforations 5 of the member 1, and there is a metallic closure-plate 21 hinged at its lower edge, as at 22, to the front of the slide 1.1 below the openings and designed to be folded up across the openings 20 to close the same, the closure-plate being held in its closed position by means of a pivotal latch or turn-button 23, mounted upon the upper portion of the front face of the slide and capable of being turned across the upper free edge of the closure-plate when folded over the openings 20. The other slidable member 10 is provided with a groove 24, corresponding to the groove 12 of the member 1, and has a short rib or tongue 25, held within the inner end of the groove 24 by means of a setscrew 26, the rib 25 of course working in the groove 12 and capable of contacting with a short rib or tongue 27, held in the left-hand end of the groove 12 by means of a setscrew 28, thereby to prevent endwise separation of the members 1 and 10. In the lower portion of the inner face of the member 10 there is a longitudinal groove 29, receiving the rib or tongue 19 of the member 1. Between the slidable members 10 and 11 there is a projection 30, carried by the front of the member 1 in the inward paths of the members 1.0 and 11., the inner ends of said members being respectively provided with notches 31 and 32 to receive the projection at the inner limits of the members 1 and 10, and thereby permit of the latter coming into intimate contact. The slidable member 10 is also provided with three sets of perforations (designated 33, 34, and .35) for successive alinement with the sets of perforations 2, 3, and 4 of the body 1, and these sets of perforations are controlled by means of a closure-plate 36,hinged to the front of the member 10 below its sets of perforations, so as to be folded up across the perforations, there being a pivotal latch or turn-button 37 mounted upon the top of the member 10 to hold the closure 36 when folded upwardly.

To illustrate the application and operation of the present ventilator, there have been shown in Fig. 1 of the drawings the lower portion 38 of an ordinary windowframe and the lower portion of a lower sash 39, the latter being slightly elevated to permit of the ventilator being inserted between the sill 40 and the bottom of the sash, the latter of course resting upon the top of the body 1, so as to hold the ventilator down upon the sill,

the slides 10 and 11 being extended to fit.

against the sides of the window-frame. As illustrated in Fig. 1, the slides 10 and 11 are separated sufficiently to expose the set of perforations 4 in the body 1, and these perforations may be controlled by the cut-ofi 6,-so as to open or close the perforations, as may be desired. The perforations of the slide 10 are out of alinement with the adjacent perforations of the member 1, while cer tain of the perforations of the slide 1 1 are registered with the perforations 5 of the member 1, the closure 21 being open.

It will here be explained that the hinges of the closure members 21 and 36 are sufficiently stiff to support each of said closures in an inclined position, as indicated by dotted lines in Fig. 3, whereby each closure is adapted to operate as a deflector to deflect the incoming current of air upwardly and above the head of a person situated adjacent the window, wherefore said person is not subj ected to a direct draft. a

From the foregoing description it will be understood that the device of the present invention is entirely complete in itself and capable of application to a window without altering or changing the latter in any manner whatsoever and does not require any extraneous fastenings to support the device in its operative position. Moreover, by means of the slides 10 and 11 the device may be adjustably extended to fit windows of different widths, and the various sets of perforations may be opened and closed at will, so as to regulate the amount of ventilation.

Having fully described the invention,what is claimed is- 1. A ventilator comprising a body having sets of perforations, a slidable member carried by the body and capable of projection beyond the body to extend the device and provided with perforations for registration with the perforations of the body, and a cutoff for the perforations of the body which are exposed by the extension of the slidable member.

2. A ventilator comprising a body having sets of perforations, a slidable member carried by the body and capable of projection beyond the body to extend the device and provided with perforations for registration with the perforations of the body, a cut-off for the perforations of the slidable member, and another cut-off for the perforations of the body which are exposed by the extension of the slidable member.

3. A ventilator comprising a body having perforations and slidable members carried by the body and capable of projection at opposite ends thereof to extend the device,said
